We're dividing 552285 by 64 
The aim is to understand the frequency of 64 in 552285.

Advancing to step 1:
The number 64 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 64

On to step 2:
64 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 64

Advancing to step 3:
If we divide 552 by 64, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 512 from 552 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 64

Step 4:
If we divide 402 by 64, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 384 from 402 to get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 64

On to step 5:
The number 64 fits into 188 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 862.0
The remainder is 60 after subtracting 128 from 188.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 64

On to step 6:
605 divided by 64 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 8629.0
If we take 576 away from 605, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
64 can be fit into 290 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 8629.4
If we take 256 away from 290, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
When dividing 340 by 64, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 8629.45
If we subtract 320 from 340, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 64, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 8629.453
Subtract 192 from 200 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 64, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 8629.4531
The remainder is 16 after subtracting 64 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 8629.45312
Subtract 128 from 160 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
320 divided by 64 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8629.453125
If we subtract 320 from 320, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8629.453125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8629.453125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8629.453125 with a remainder of 0.0.
